ClearInvestigation of Abundance and Spatial Distribution of Marine Debris on Ghanaian Urban Coastal Beaches
Marine debris abundance and spatial distribution were comprehensively assessed on three urban coastal beaches in Ghana along the Gulf of Guinea. The study characterized debris types and distribution patterns, documenting significant plastic accumulation with implications for coastal ecosystem health, public safety, and eco-tourism.
Solid Waste Management in Coastal Ghana
This paper assessed solid waste management challenges in coastal communities of Ghana, finding that inadequate infrastructure leads to plastics and other waste being dumped directly into coastal waters or on beaches. The study highlights how waste management failures in developing coastal regions directly drive marine plastic pollution.
The Health-trash Nexus in Challenging Environments: A Spatial Mixed Methods Analysis of Accra, Ghana
This mixed-methods study in Accra, Ghana analyzed the spatial relationship between waste disposal practices and health outcomes in a rapidly urbanizing city. Open dumping and poor waste management create conditions where microplastics and other contaminants accumulate near communities, with direct public health consequences.
The Coastal Environment of Elmina in Ghana - Appraising the Causes and Effects of Coastal Pollution
This study examined coastal pollution in Elmina, Ghana, one of the country's major tourist destinations, finding that marine debris including plastic waste has severely degraded the coastline and reduced its appeal for tourism. The research highlights how inadequate waste management in developing coastal communities creates environmental and economic harm.
Assessing microplastic contamination levels in ghana's mangrove wetlands
Researchers investigated microplastic contamination levels in Ghana's mangrove wetlands, examining how the morphology of mangrove root systems traps and accumulates plastic particles of all sizes and assessing the threat posed to these ecologically critical coastal ecosystems.
Assessing microplastic contamination levels in ghana's mangrove wetlands
Researchers assessed microplastic contamination levels in mangrove wetlands in Ghana, examining how mangrove tree morphology facilitates plastic accumulation and what concentrations and polymer types are present in these coastal ecosystems. The study addressed threats to mangrove ecological services including water quality improvement, carbon sequestration, and coastline protection posed by plastic pollution.
Microplastics in Ghana: An in-depth review of research, environmental threats, sources, and impacts on ecosystems and human health
This review examines the state of microplastic research in Ghana, finding that contamination is widespread across coastal areas, rivers, lakes, and forests. Most studies have focused on coastal environments, leaving significant knowledge gaps about inland pollution and its effects on the communities that depend on these ecosystems. The review calls for systematic policy frameworks and more targeted research to protect both ecosystems and human health in Ghana.
Numerical Modelling of Plastic Debris Transport and Accumulation throughout Portuguese Coast
Researchers applied numerical modelling to simulate the transport and accumulation of plastic debris along the Portuguese coast, assessing how ocean currents drive microplastic dispersal and deposition patterns in this Atlantic coastal region. The study contributes spatial predictions of plastic accumulation hotspots to inform monitoring and management strategies.
Quantifying Plastic Waste and Microplastic Contamination in African Aquatic Systems: An Imperative for Sustainable Waste Management
This review assessed the scale of plastic waste and microplastic contamination in African aquatic systems, finding that inadequate waste management infrastructure amplifies plastic pollution in rivers, lakes, and coastal waters across the continent.
Marine Litter Sources and Distribution Pathways
This book chapter reviews the sources and distribution pathways of marine litter in African coastal environments, highlighting gaps in research and the need for targeted policies to address plastic pollution along African coastlines.
Marine plastic pollution in West Africa – the case of Ivory Coast
Researchers documented marine plastic pollution in Ivory Coast, West Africa, measuring plastic inputs, concentrations in coastal environments, and characterizing polymer types. With annual per capita plastic consumption of 19-26 kg and poor waste management infrastructure, the country faces rapidly growing plastic pollution pressure with inadequate monitoring in place.
Characterisation of Macro-plastic Waste Along the Philippines' Longest Coastal Boulevard: Basis for Solid Waste Management and Policy Formulation
Researchers characterized macro-plastic waste types and quantities along the Philippines' longest coastal boulevard, using density and cleanliness metrics as a basis for solid waste management and policy formulation. The study identified dominant plastic categories and spatial distribution patterns, providing empirical data to inform targeted waste management interventions and coastal protection policies.
Innovative Use of Plastic for a Clean and Sustainable Environmental Management: Learning Cases from Ghana, Africa
This paper documents innovative approaches in Ghana where plastic waste is creatively converted into artifacts and pavement blocks rather than being discarded. The study suggests that these community-driven recycling initiatives help reduce plastic waste volumes, address urban drainage problems, and offer scalable learning cases for environmental sustainability in developing countries.
Characterization and Spatial Abundance of Microplastics in the Coastal Regions of Cox’s Bazar, Bangladesh: An Integration of Field, Laboratory, and GIS Techniques
This large-scale field and GIS study characterized microplastics in coastal sediments of Cox's Bazar, Bangladesh, finding high concentrations linked to tourism pressure, inadequate waste management, and the proximity of rivers carrying inland plastic waste.
Assessing the Environmental Impact of Urban Plastic Waste in Pahang, Malaysia
Researchers assessed the environmental impact of urban plastic waste in Pahang, Malaysia, surveying plastic accumulation in waterways, land, and coastal areas and estimating pollution loads from different urban sources.
Quantitative Analysis of the Sized Ranged Plastic Debris on Beach Shoreline along the Limbe Coastline, Cameroon
Researchers quantitatively assessed the abundance and distribution of plastic debris across four size classes on five sandy beaches in Cameroon, collecting 12,822 particles over 80 sampling quadrants and characterizing accumulation patterns along the coastline.
A review of plastic debris in the South American Atlantic Ocean coast – Distribution, characteristics, policies and legal aspects
Researchers compiled and reviewed studies on plastic debris along the entire South American Atlantic coast, covering distribution patterns, types of plastic, and existing policies. They found that macroplastic items like packaging and cigarette butts dominate beach litter, while microplastic contamination is widespread in water and sediment across the region. The review highlights significant gaps in research coverage and inconsistencies in national regulations that hinder effective plastic pollution management.
Macro impacts of plastic pollution in Ghana
Researchers applied qualitative system dynamics causal modelling to assess the macro-level impacts of plastic pollution in Ghana and West Africa, constructing a hierarchical framework linking high-level and low-level pollution effects across environmental, economic, and social dimensions. The systems thinking approach aims to inform effective policy development for preventing and mitigating plastic pollution in the region.
Understanding the socioeconomic determinants of marine plastic pollution: Evaluating policy effectiveness and mitigation strategies in the Global South.
